Reissued Feb. 3, 1931 UNITED STATES PATENT OFFICE EDWARD M. ANDRES, orGUNNISON, COLOR-ADO, ASSIGNOR 0F ONE-HALF T0 RUSSELL w. TALLMAN, orGUNNISON, COLORADO GRAPHIC CHART Original No. 1,713,811, dated May 21,1929, Serial No. 210,084, filed August 2, 1927. Application for reissuefiled August 26, 1929.

My invention relates to graphic charts, and especially to charts thatshow comparatively the progress made in certain subjects or by variousindividuals.

An object of the invention is to provide such a chart that is easilyaltered from time to time to indicate such progress.

Another object is to eliminate the use of curves in denoting progressbecause of the confusing nature of a number of curves superimposed onthe same chart, and to provide a compact chart that may be used for anun1- ber of subjects or individuals without confusion.

A further object is to provide a plurality of distinguishable scales foreach subject or individual.

Other objects reside in details of construc-' tion which will more fullyappear in the course of the following description.

In the drawings, in which like reference characters designate like partsin the several views,

Figure 1 designates a face view of a chart embodying the foregoingfeatures;

Figure 2, an enlarged view of a portion of a modified form of the chart;and

Figure 3, an enlarged section taken on the line 3-3, of Figure 1.

Referring more specifically to the drawings,the chart is composed of aback member 5 and a face member or sheet 6 fastened upon the back.

The face of the back member 5 preferably is of a distinctive color,black being shown on the drawings, and the face of the sheet 6 has acolor contrasting with that of the back.

The sheet 6 is preferably ruled horizontally as at 12, and vertically asat 8. In the drawings the vertical ruling is divided by heavier lines14: into groups of twenty hereinafter called columns.

The sheet 6 has furthermore a number of removable strips 9 divided byparallel perforated or otherwise weakened lines 9a. Each of thehorizontal divisions of the sheet is shown as having one or more ofthese strips, and spaces 13 are provided atan end of the removablestrips for insertion of'the names of subjects, individuals, teams,shifts, and

the like. Spaces 15 may be provided at the heads of the columns forconsecutive numbers 16.

The sheet 6 is by means of a suitable adhesive shown at 7 in Figure 3,pasted upon the face of the back member over its entire extent exceptingspaces 10 corresponding with the narrow strips 9 defined by the weakenedlines 9a so that the strips may be torn out of the These percentages areon the basis of 100%.

In the use of the chart for school purposes, the names of the subjectsor pupilsare placed in the spaces 13. After the grade of a pu il isdetermined for the first unit of work an examination, a months average,a weeks attendance, a theme, or whatever the unit is), the respectivestrip is torn off a corresponding distance. For instance, if the gradeis 80% for the unit of work, the strip is torn off sixteen of the twentyspaces in column No. 1, as indicated by the carets- 20 and 21 inFigure 1. The caret 20 represents the grade for the unit of work and thecaret 21 represents the cumulative grade to date. Of course they are thesame for the first unit.

The earnings of the pupil for the second unit are indicated withreference to the designations in the tiers by still further tearing therespective strip from the sheet fastened upon the back of the chart andin this manner the progress made by the pupil is graphically shownwithout the use of curves.

It will be noted that the removal of the strips exposes the face of theback member of the chart which as stated before is colored in contrastwith the face of the superimposed sheet so that the grade indicationsare clearly distinguishable-and easily read. It will also made by schoolpupils or others intheir respective occupations by reference to thetiers of grade designations above the ruled body portionof the chart hasbeen made the sub- ]ect of a separate applicationforpatent Se-j rial No.210,085, filed August 2, 19271 No further explanation of the method istherefore necessary at thistime. v The modified form shown in Figurevaries from that just described and shown, only in that (a) the back 5ahas a series of stripes preferably. of different colors,green, red, andblack for example, indicated incolors or by distinctive cross-hatchingas in the drawings, the sheet 6 has between the lines 12, pluralities ofremovable strips corresponding with'the series of stripes, and (c) thespaces for the names of the subjects or individuals are opposite thepluralities of strips instead of one as in the first described form.

In using the modified form, the same pro-- cedure may be followed exceptthat-the plu'-,

rality of removable-strips 26, 27 and 28 0pposite each name mayrepresent three branches of study, such as spelling, arithmetic andgrammar, of the same-pupil.

Inasmuch as the stripes on the face of the background beneath theremovable strips are differently colored, the progress madein thedifferent branches of study is readily seen without the possibility ofconfusion as might occur incase the background had but one color as inthefirst described form of the invention.- l v I It is to be noted thatin both forms ofrthe invention, the face of the back sheet which isclearly differentiated from that of the top sheet by reason of itscontrasting color, is the medium which'in cooperation with the scale ofthe top member, indicates the standing of the student in a branch oflearning, and that by-gradually reducing the length of the respectiveremovable strip of the top-sheet, the advance of the .pupil insaidbranch, is progressively indicated:

What I claim and desire to secure by Letters Patent is V 1. A chart ofthe character described comprising a base member having a multi-coloredbackground and upon the same, a face member of contrasting color,provided with removable strips between weakened lines, the

(Eli

strips corresponding in position with the different colors of thebackground, and the face member being fastened upon the base memberexclusive of the strips whereby the latter may be torn out to expose thebackground beneath them.

2. A chart of the character described comprising a. basemember providinga background and upon-the same, a ruled face member of contrastingcolor, provided in trans verse relation to its ruling with removal 1strips, the-face-member' being fastened upon "the base member exclusiveof the strips whereby the latter may be progressively removed to exposethe background beneath them.

3. A chart of the character described comprising a base vmember having abackground of series of differently colored stripes, and upon thevbasemember, a face member having. series of removable strips correspondingin positionwith the series of stripes, the facemember being fastenedupon the base member. exclusiveof the strips whereby the latter may beremoved to expose the background.

4. A chart of the character describedcomprising a base member havingamulti-colored background, a face member upon the basemember providedwith removable strips cor.- responding in position with the colors ofthe background, a portion of the face member other than the removablestr-ipsbeing fastened upon the base member,whereby all or v a portion ofeach strip may be separately removed to expose the background. 3 V

5. A graph-chart for indicating variable conditions, comprising a backsheet and atop sheet held. thereon, the top sheet having a strip betweentwo tearing-lines tobe severed in selective lengths from the body of thesheet, the face of the back sheet exposed b the removal of the strip,contrasting with the face of the top sheet to accentuate the extent ofthe severed portion of the strip and the face of the top sheet bearing:indici'a to measure the length of the severed portion of the strip. l I

6. A graph-chart com-prising aback-sheet and an indicative top sheetheld thereon, the top sheet having a strip defined by determinatetearing-lines. to be severed from ,the body of the sheet in selectivelen ths whereby to expose the face of the back 5 eet, and the faceof theback sheet contrasting'withthe face of the top sheet to accentuate thelength of the severed portion of the strip.

7. A-graph-c'hart comprisingqaback sheet and an-indicati-ve top sheetheldthereon, the

ibo

top sheet having a strip between two te ari-ngilines to besevered fromthe body of the sheet in selective lengths whereby to expose the afterall or a portion of the strip has been removed.

9. A graph-chart comprising a back sheet and atop sheet held thereon,the top sheet 5 having a strip defined between two tearinglines to beseveredfrom the body of the sheet in selective lengths whereby to exposethe face of the back sheet and the top sheet hearing indicia to measurethe length of the severed portion of the strip.

10. A graph-chart comprising a back sheet and a top sheet held thereon,the top sheet having a strip defined between two tearinglines to besevered from the body of the sheet in selective lengths whereby toexpose the face of the back sheet and the top sheet bearing graduationsin transverse relation to the strip.

11. A graph-chart comprising a back sheet and an indicative top sheetheld thereon, the top sheet having a plurality of parallel stripsdefined between tearing-lines to be severed from the body of the sheetin selective lengths for comparative measurements, and the face of theback sheet exposed by the removal of the strips contrasting with theface of the top sheet to accentuate the lengths of the severed portionsof the strips.

In testimony whereof I have aflixed my signature.
